TimePeriodMode Wizard option

A trend time period is the interval of measured values shown on the X-axis of the trend, which consists of a start time, end time, and a duration. TimePeriodMode provides options to specify the type of time period shown by a trend.

• Fixed: In a Fixed trend period, the start time is initially the current time. The start time of a trend period does not change automatically and can be specified by a script using the StartTime property. The end time of a Fixed trend period is set by the duration of the trend from the specified start time of the period. The EndTime property is read only.

  In a Fixed trend time period, a trend updates from the left with the most current measured value shown at the left margin of the trend grid.

• Moving: In a Moving trend period, the end time of a trend period is the current time. The end time is the duration of the time period from the start time.

  In a Moving trend period, a trend updates from the right with the most current measured value shown at the right margin of the trend grid.

  Note: When the Meter Wizard option is set to True for a SA_Trend_SinglePen symbol, a meter can be shown at the right margin of a trend set to a Moving time period.
